Im thinking of buying 2008 Audi S5 in a month or so, looking for something that has most of the equipment it can have so theres a few questions i need to clear up.

Do all of the 2008 audi S5s have Bang and Olufsen sound system as standard or its optional? How many speakers does it have? If its optional, is there any visual way to confirm its the Bang and Olufsen.

Also does the rear camera come as an option or it comes as standard with parking sensors?

Can you guys give me a some suggestions what to look out for on the s5.

At the moment my wanted list consists of:
-Bang and olufsen sound system
-Keyless go
-Black Interior (well the roof part)
-Full leather

Car color choise would go black/white or meteor grey.

Sunroof and rear camera would be nice too but it seems to be too hard to find something that has most of it.
